Slope (m) =
ΔY
ΔX
=

= 1.3333333333333
θ =
arctan( ΔY ) + 180°
ΔX
= 233.13010235416°
ΔX = -3 – 3 = -6
ΔY = -6 – 2 = -8
Distance (d) = √ΔX2 + ΔY2 = √100 = 10
Equation of the line:
y = 4/3x – 2
When x=0, y = -2
When y=0, x = 1.5
D.
Answer:
just take the 96 and 66 and middle it then take y multiply that=answer
Step-by-step explanation:
<u>If two lines are perpendicular to each other, their slopes</u>
<u>are negative inverses of each other.</u>
Thus,
. See how this works?
We took 4, then took its opposite, and flopped that over
Definition-:
Perpendicular lines are lines that intercept each other at a 90 deg. angle, which is usually called the right angle.
Answer:
x=20[vertically opposite angle are equal]

Answer:
6,364.8 lb
Step-by-step explanation:
The centroid of the plate is its center, so is 1.5 ft above the bottom of the pool, or 8.5 ft below the surface. The area of the plate is (3 ft)(4 ft) = 12 ft². Then the fluid force is ...
(62.4 lb/ft³)(8.5 ft)(12 ft²) = 6,364.8 lb
